Tablets for Poollab Copper No.1 (copper) (10 tablets)

The Copper No.1 reagent tablets are the first of the pair of tablets used for the colorimetric measurement of the copper content (Cu²⁺) in pool water using the Poollab digital photometer. The tablet reacts with the copper ions in the water sample and creates a coloured complex, the intensity of which the photometer evaluates as the copper content. Copper is added to pool water as part of algicidal products based on copper sulphate; regular measurement prevents exceeding the recommended concentrations and the possible discolouration of the water or the bathers‘ hair. The pack of 10 tablets provides a supply for repeated measurement throughout the season. Store in a dry place and protect from direct sunlight.
